OLIVEIRA, Rone Batista de et al. Yield of seedling species forestry of four using different substrates and development in field. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp. 122-128. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542008000100018.
This experiment was installed with the aim of evaluating the substrates effect with different chemical and physical characteristics in the formation of seedling of Cedrela fissilis Vell. (cedro rosa), Eucalyptus grandis W. Hill ex Maiden (eucalipto), Acacia holocericea A. Cunn. ex G. Don (acacia) and Schinus terebinthifolius Raddi (aroeirinha) produced in tubes of 55 cm3. The substrates had been constituted of several combinations of the following materials: húmus of earthworm, tanned cattle manure, fertilizer of hen, turf, rind of processed peanut, carbonized rind of rice, coffee straw. The experimental outline used was entirely randomized. The morphologic parameters of seedling and their relations were evaluated. The pits were filled with two types of fertilization: cattle manure and cattle manure + conditioning of soil in field. The data were submitted to the analysis of variance and the test of average (Newman-Keuls 5%). The results obtained in the nursery stage that can be recommended for production of seedlings of the studied essences were the base substrates of earthworm humus, peanut peel processed and peat. In the field stage, except for the species acacia, for the variable height of the plants, the fertilization with cattle manure + conditioning of soil was the best for all the appraised variables, providing better development of the seedlings in relation to the fertilization with cattle manure only.
